devg_get_miscfuncs()

Get a table of your driver's miscellaneous 2D drawing functions

Synopsis:

int devg_get_miscfuncs (disp_adapter_t *ctx,
                        disp_draw_miscfuncs_t *fns,
                        int tabsize);

Description:

A 2D driver must provide an entry point called devg_get_miscfuncs(). The graphics framework calls it to get a table of your driver's miscellaneous 2D drawing functions.

The arguments are:

ctx

A pointer to the disp_adapter_t structure that describes the graphics adapter.

fns

A pointer to a disp_draw_miscfuncs_t structure that your driver must fill with pointers to its miscellaneous drawing functions.

tabsize

The size of the table, in bytes.

Use the DISP_ADD_FUNC() macro to add function pointers to the table. It checks the tabsize argument and adds a function pointer only if there's space for it in the table.

Returns:

0

Success.

-1

An error occurred.

Classification:

Neutrino
